Defense Acquisitions: Departmentwide Direction Is Needed for Implementation of the Anti-tamper Policy

Description: A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) invests billions of dollars on sophisticated weapon systems and technologies. These may be at risk of exploitation when exported, stolen, or lost during combat or routine missions. In an effort to minimize this risk, DOD developed an anti-tamper policy in 1999, calling for DOD components to implement anti-tamper techniques for critical technologies. In March 2004, GAO rep… more

Aviation Weather: FAA Is Reevaluating Services at Key Centers; Both FAA and the National Weather Service Need to Better Ensure Product Quality

Description: A letter report issued by the Government Accountability Office with an abstract that begins "The National Weather Service's (NWS) weather products are a vital component of the Federal Aviation Administration's (FAA) air traffic control system. In addition to providing aviation weather products developed at its own facilities, NWS also provides staff on-site at each of FAA's en route centers. This group of NWS meteorologists--called a center weather service unit--provides air traffic managers wi… more

Hydrogen Fuel Initiative: DOE Has Made Important Progress and Involved Stakeholders but Needs to Update What It Expects to Achieve by Its 2015 Target

Description: A letter report issued by the Government Accountability Office with an abstract that begins "The United States consumes more than 20 million barrels of oil each day, two-thirds of which is imported, leaving the nation vulnerable to rising prices. Oil combustion produces emissions linked to health problems and global warming. In January 2003, the administration announced a 5-year, $1.2 billion Hydrogen Fuel Initiative to perform research, development, and demonstration (R&D) for developing hydro… more

Fluidized Bed Steam Reforming Mineralization for High Organic and Nitrate Waste Streams for the Global Nuclear Energy Partnership

Description: Waste streams that may be generated by the Global Nuclear Energy Partnership (GNEP) Advanced Energy Initiative may contain significant quantities of organics (0-53 wt%) and/or nitrates (0-56 wt%). Decomposition of high nitrate streams requires reducing conditions, e.g. organic additives such as sugar or coal, to reduce the NO{sub x} in the off-gas to N{sub 2} to meet the Clean Air Act (CAA) standards during processing. Thus, organics will be present during waste form stabilization regardless of… more

Syntheses, Structure, Magnetism, and Optical Properties of the Interlanthanide Sulfides delta-Ln2-xLuxS3 (Ln = Ce, Pr, Nd)

Description: {delta}-Ln{sub 2-x}LuxS{sub 3} (Ln = Ce, Pr, Nd; x = 0.67-0.71) compounds have been synthesized through the reaction of elemental rare earth metals and S using Sb{sub 2}S{sub 3} flux at 1000 C. These compounds are isotypic with CeTmS{sub 3}, which has a complex three-dimensional structure. It includes four larger Ln{sup 3+} sites in eight- and nine-coordinate environments, two disordered seven-coordinate Ln{sup 3+}/Lu{sup 3+} positions, and two six-coordinate Lu{sup 3+} ions. The structure is c… more

Transient Accident Analysis of the Glovebox System in a Large Process Room

Description: Local transient hydrogen concentrations were evaluated inside a large process room when the hydrogen gas was released by three postulated accident scenarios associated with the process tank leakage and fire leading to a loss of gas confinement. The three cases considered in this work were fire in a room, loss of confinement from a process tank, and loss of confinement coupled with fire event. Based on these accident scenarios in a large and unventilated process room, the modeling calculations o… more

T Tank Farm Interim Surface Barrier Demonstration -- Vadose Zone Monitoring FY07 Report

Description: CH2M HILL Hanford Group, Inc. is currently in the process of constructing a temporary surface barrier over a portion of the T Tank Farm as part of the T farm Interim Surface Barrier Demonstration Project. The surface barrier is designed to prevent the infiltration of precipitation into the contaminated soil zone created by the Tank T-106 leak and minimize movement of the contamination. As part of the demonstration effort, vadose zone moisture monitoring is being performed to assess the effectiv… more

Groundwater Availability Within the Salton Sea Basin Final Report

Description: It is widely recognized that increasing demands for water in Southern California are being affected by actions to reduce and redirect the amount of water imported from the Colorado River. In the Imperial Valley region, for example, import reductions will not only affect agricultural users but also could produce significant collateral impacts on the level and quality of water in the Salton Sea, its regional ecology, or even the long term air quality in the greater basin. The notion of using grou… more

Syntheses, Structure, Magnetism, and Optical Properties of the Partial Ordered Quaternary Interlanthanide Sulfides PrLnYb2S6 (Ln = Tb, Dy)

Description: Dark red single crystals of PrLnYb{sub 2}S{sub 6} (Ln = Pr/Yb, Tb, Dy) have been synthesized through the reaction of elemental rare earth metals and S using a Sb{sub 2}S{sub 3} flux at 1000 C. These isotypic compounds adopt the F-Ln{sub 2}S3 three-dimensional open channel structure type. Eight-coordinate Pr{sup 3+} ions sit in the channels, which are constructed from three different edge-shared double chains running down the b axis, which contain Yb(1)S{sub 6} octahedra, Yb(2)S{sub 6}, octahedr… more

MODELING THE UREX-PLUS-3A PROCESS USING ASPEN PLUS COUPLED WITH AMUSE

Description: A plant level simulation of the UREX+3a separations process has been developed using AMUSE for solvent extraction calculations coupled with Aspen Plus for other operations. AMUSE, an Excel based application developed at Argonne National Laboratory [1], performs a rigorous calculation of countercurrent solvent extraction processes using thermodynamically based distribution coefficients specifically designed for nuclear separations. Aspen Plus [2] models simulate other separations plant operation… more

RADIATION EFFECTS ON EPOXY/CARBON-FIBER COMPOSITE

Description: Piping in the Defense Waste Processing Facility (DWPF) at the Savannah River Site (SRS) must withstand the stresses involved during an unlikely but potential deflagration event. One method proposed for protection and reinforcement of piping during such an event is the use of a carbon fiber-reinforced epoxy composite (Diamond-Wrap{reg_sign}). In the DWPF, this reinforcement composite product would be required to maintain its safety function for a 20-year service life. This product has been ASME-… more

Regulation of Vehicle Greenhouse Gas Emissions: State and Federal Standards

Description: This report discusses the federal Corporate Average Fuel Economy (CAFE) standards (including tighter standards enacted under P.L. 110-140) and compares them with the GHG standards under California’s law. It also identifies some factors that would have a bearing on the relative stringency of CAFE and the California program.
